Answers :

If you have digital multimeter, and a little background in electronics. See the power supply tag. It bears some important specification like Output voltage and if it is a DC voltage and polarity. Commonly it is near 20Vdc output setting the multimeter to read that voltage say 50Vdc read.

Probe the end chord. If you get some voltage reading wiggle the chord to check if it have some broken wire to check or broken connection. If the reading comes off, probably the wire has connection problem. Then the power supply has the problem. If it is okay then it is on the laptop.

Ok if you don't have a little background in electronics better not to open that power supply high voltage inside and it can kill.

If you have background and knowledge on power supplies. Sometimes it have a notch clip that still holding it or you have to open one side first. Or it have some double adhesive tape inside.

Goodluck, hope I give you some input.

Yes it is damaged. You would have to re-solder the A/C port back onto the motherboard so it gets a good connection. Most laptops come apart from the top. i.e. Take off the Hinge Cover, Keyboard, LCD Panel, Palm Rest, and then you will be able to see the motherboard. The port should be visible, but it will be easier to solder if you remove the motherboard from the bottom plastics. Then solder it, I have never attempted this because I am not good at soldering.
\015\012Or buy a new motherboard.
\015\012P.S. The screws you took out on the bottom actually screw up into the palmrest, they do not hold the "bottom" on. They hold the palmrest to the bottom. (the palmrest is the BIG plastic thing with the mousepad attached to it)
\015\012Good luck.
